    Bladder leaks contained

    I've tried several brands, that leak right through. So far these haven't. There seems to be more than one layer in them.

    Sometimes I have quite a bit leakage, that spill over the sanitary pad. So I'm pleased these have not . It does say not to Wash in hot and use hot dryer, use cold water, . Then air dry. (For longer life)? I use very short coolest temp in dryer. Ide but more but cost is a factor. They are very comfortable too.
